Residents plan campaign against mega hog farms
Posted in: Environment by admin on January 1, 1997 | No Comments
A letter-writiing campaign is planned by a citizens coalition in the Ashfield Township against intensive farming operations, in reaction to a permit issued to a 3 400 hogs farm. Those letters will be sent to Noble Villeneuve, ag. and rural affairs minister and also to other ministries including health, environment and economic development.
A moratorium is also demanded by PROTECT on 2 500 hogs and more farms. PROTECT are concern with the impact of those farms particularly considering the environmental outcomes in North Carolina, Iowa and elsewhere. The three fish killer spills this year in the township also aggravated the concerns.
Bill Andrews emeritus prof. at the env. studies at Toronto Univ. invited to a PROTECT meeting also rised concerns pointing out the situation in North Carolina and questionning the lagoons as proper way to store the manure. He goes futher asking why factory farms shouldn’t have waste management plans as urban developpers have to produce before building. He sees another way to control the problem in limitating the number of animals and septic systems a given watershed can sustain. He also advise the residents to ask the government to clarify some elements of the Bill 146 particularly concerning the defintion of the “normal farm practice” and also whether the farmers will be exempted from the Environmental Protection Act.
Members of the group mentioned the deteriorating quality of the water and the fact that money is spent on beachfront for swimming purpose. Where will the people swim if the beaches are closed.
Joe Gleason (an america) mentioned that he sold his property in Michigan to settle along the lake and he is worried about the situation. He also is at the head of the Huron’s edge a news letter dealing with pollution problems.
Some of the proposed actions are quite drastic and don’t offer much viable solutions for the existing facilities (septic systems and farms) that cause problems now, it is not sufficient to ban expansion. It would be more productive to see how the situation could be controlled including the expansion project. The watershed approche proposed is probably the best element of this article.
A Survey on Concrete Floors in Pig Houses and their Degradation
Posted in: Environment by admin on | No Comments
On farms with fattening pigs , degradation of slatted and solid concrete floors can result in animal injuries and early failure of slat beams . A survey in East and West Flanders was conducted to gauge the extent of this problem , the causes and consequences . Entrusting mixing and placing of the concrete to specialized firms , appeared to increase the life of the floor . However , even concrete slats cast by specialized manufacturers , showed degradation within five years of use on 40% of the farms . No relation could be found between the use of high-pressure cleaning and the speed of attack . The use of cleaners seemed to delay the attack rather than cause degradation . The
feeding method had a major influence on attack . The smaller the distance between water and feed supply , the faster the degradation proceeded . Therefore the use of liquid feed made the problems significantly worse . Almost half of the farmers had already taken measures to protect or repair the floor . The life of coatings appeared to be rather limited . Surface layers with ordinary portland cement and a

The results presented are from an important survey on many livestock buildings. A more complete statistical study could have given more information on the accuracy of the results.
Slurry Cooling to Reduce Ammonia Emission from Pig Houses
Posted in: Environment by admin on | No Comments
1 Dfl = $0.7177 CAN (01/17/98)
For the sows, the extra annual costs for such a cooling system would be per place equal to $85.40 CAN; for growing-finishing: $16.50 CAN/ place; for weaned piglets: $6.96 CAN/place and, for dry sows: $32.30 CAN/place. The investment costs for a cooling slurry system would vary depending on the farm size and the availability of the water and the local regulation on ground water use. Lowering the temperature in the superior layers of the stored manure results in lower ammonia emissions. The reduction obtained brings the ammonia emissions under the Dutch Green Label Standard. Because of the important cost of such a system, the use of it has promises only where incentive and regulation are enforced.
Field Tests of Bio-additives to Reduce Ammonia Emission from Pig Houses
Posted in: Environment by admin on | No Comments
Looking at the results and the statistical analysis, it is not possible to find significant differences between the emission rates measured with the use of additive and without the use of additive. More analysis or more tests should be done to explain the differences obtained.
